You're speculating and I don't necessarily agree with that statement.
Quite frankly, if they are less inclined to be cooperative because they are going to have to wait for 40 years for parole, they shouldn't be let out in the first place. They shouldn't be let out in 25 years. Let's face it; if they're that type of person who is not remorseful and is not willing to understand the gravity of the crime and that they have an obligation to society to fulfill that punishment, then quite frankly, they shouldn't be paroled earlier than whatever the judge decides.
